54F 74F280 9-Bit Parity Generator Checker August 1995 54F 74F280 9-Bit Parity Generator Checker General Description The ’F280 is a high-speed parity generator checker that accepts nine bits of input data and detects whether an even or an odd number of these inputs is HIGH If an even number of inputs is HIGH the Sum Even output is HIGH If an odd number is HIGH the Sum Even output is LOW The Sum Odd output is the complement of the Sum Even output Features Y Guaranteed 4000V minimum ESD protection Commercial 74F280PC Military Package Number N14A Package Description 14-Lead (0 300 Wide) Molded
